The Tennessee Republican has asked multiple members of the GOP brass, including the president and Senate Majority Leader Mitch McConnell, for advice as he weighs whether to re-up for another term or return to the private sector, where he was a construction and real estate titan before entering public service.

“As far as what am I going to do in the future, I’m still contemplating the future,” Corker told CNN last week. “It’s a tremendous privilege to do what I do, and to weigh in on the big issues.”

He told reporters later in the week that he will decide on his future “very, very soon.”

McConnell, now joined by the president, has urged Corker to run again, a source familiar with their conversations told CNN.

Corker, who Trump once considered tapping as his running mate in 2016, sat on $6.5 million in his campaign war chest at the end of the most recent reporting period. His office told The Tennessean it has raised an additional $1 million. Corker’s campaign fund is the most flush of any Republican facing re-election in 2018.

In August, Trump and Corker exchanged verbal blows in the wake of Trump’s handling of the racially motivated violence at a white supremacist rally in Charlottesville, Virginia.

When Trump said “many sides” shared blame for the violent outbursts there, Corker said the president had neither the “competence” nor the “stability” to be successful leading the country.

Trump shot back with a tweet calling the senator’s statement “strange” considering Corker has come to Trump for advice on his re-election in Tennessee. The president also alluded to Corker’s chances of winning a third term there, adding, “Tennessee not happy!”

Strange statement by Bob Corker considering that he is constantly asking me whether or not he should run again in '18. Tennessee not happy!

If he wants to stay in Washington, Corker will have to stamp out at least three primary challengers, including conservative operative Andy Ogles, who recently headed the Koch brothers-backed Americans for Prosperity in Tennessee and announced his bid last week.
